Kalego was unapproachable, sour, mean. His students practically cowered before him. Of course he was an excellent teacher, he took great attention in each of his students, worked on their weak spots, and pushed them to aspire for perfection, but that didn't mean he'd ever be soft for anybody. Until you. Desire. Desire was the biggest driving factor in a demon's life. Demon's cannot resist temptation.That is the truth that reigns supreme in the nether world. You were his temptation.
